A proper choice of the preheating process as a function of the air temperature, the welding velocity, the air nozzle geometry, and the part thickness results in a typical multilayer structure in the weld for which the weld zone
will not fail in short- and long-term tests.
Injectiweld" system is a hand-held welding gun that continuously feeds and melts a rod of thermoplastic (HDPE, ABS, PP, PS) and extrudes it under pressure as a continuous bead in the weld zone
Voiding may be reduced using lower hot plate temperatures and higher welding displacements, but that results in an increase in the transverse orientation of the talc particles in the weld zone
Drader's Injectiweld handheld welding gun continuously feeds and melts a plastic rod, then extrudes it under pressure into the weld zone
5) has a narrow weld zone
with a highly oriented texture.
The corresponding weld zone
(longitudinal, cross-thickness) thicknesses in millimeters were (0.

The degree of crystallinity is a bit lower in the weld zone
than next to it.
Therefore, in order to understand the weldline characteristics of polymer blends, it is necessary to have a clear knowledge of weld zone
morphology and its formation mechanism during molding processes.
The values at 150[degrees]C are particularly relevant from the user's point of view, as they indicate the tendency of the tape to contract near the weld zone
27 mm to assure that the weld zone
does not contain any material from the molded skin layer.
17, the first tests on irradiated material were performed at ORNL with a laser welding technique (see video below) that uses a primary laser to weld and secondary beams to reduce tensile stresses near the weld zone
(a patent application has been submitted).
